WITNESSES C INVENTOR Z m6 IC/N in configuration What I term a soundspiral or the configuration of a nautilus shell when viewed in atrans-axial section. Furthermore, this cup also simulates the tympanumof the human ear and the individual gToWthpartitions of the nautilusshell. This cup 2 may be suitably supported as by'friction or bysoldering from the three Wires D at the points 3, e and I prefer thatthe contour and configuration of this cup 2 be such that the eccentriccupola or umbo 6 of the cup be located in the proportionate distancefromthe points 3, at and 5, respectively 3, a and'5 units as shown inthe drawings. 1

likewise prefer to locate the cup 2 Within the conical receptacle Gsubstantially, so

that the points 3, i, and 5 are r spectively at distances in theproportions 5, a and 8 from the most adjacent portions of theinterior-of the conical receptacle G, all shown in the drawings.

I preferably construct vthe cup 2 of size so that its content-volumeapproice inates the contentvolume of the mouth cavity of the human voiceanatomy.

A rod E projecting through the ring K at the end of the conical receptcted with a chuck and set screw; purpose of holding a suitable vibrationcooperator shown in the form of a stylus N. This rod E is suitablyextended and secured to thenmbo 6 of the cup In this Way I have provideda vibratory medium in the form of the cup :2 which I vmay describe ashavingvibratory functions in planes of many directions and also ashavingvibratory pitch periods coiirdinating in the proportion 3, 4i and5, just as is present in the tympanum of the hum-an ear.

The better to carry out further refine ments in sound functioning Ipropose the employment not merely of a single vibratory means such asthe single cup 2 hut contemplate in amplification the employment of acomplete nest or set of cups A oil which I have shown eight in all,seven nested Within the cup 2. Likewise, l". have appreciated theadvantage of the employment of a plurality of nests of cups and haveillustrated three nests, B and (l in addition to the nest A. In the nestB the cup 2 I prefer to form of a volumetric capacity equivalent to thevolumetric capacity of the nasal cavities of the human voice (i isfittor the.

of the cups of the various sets regardless of how many or how many cups111 a set are employed, so that sound vibrations from each cup aretransferred to and through the rod E to the stylus N, or vibrations aretransferred from the stylus N to and through the rod E to reproduced assound by the cups.

It is who understood that the conical receptacle G and the spiral horn lare useful in amplifying the sound or vibrations made through thefunctioning of the cup or cups and that the positioning of each cuppermits sound reflection Without interference.

"What I claim and WhatI desire to secure by United States Letters Patentis:

1. In a sound-functioning mechanism, a vibratory medium in the shape ofan eccen tric cuphaped diaphragm; and vibration transmitting meanscooperating with said diaphragm at the umbo of eccentricity,

2. in sound mechanism, a sound diaphragm having a substantially circularperiphery and being cup-shaped with the locality of maximum displacementspace-d in substantially the proportion of 3, 4: and 5 from threeequi-distant points at the periphery of the diaphragm.

3. In sound mechanism, a diaphragm approximating the shape of thetym-panum of the human ear; and a transmitter of vibrations cooperatingwith said diaphragm at the locality corresponding to the umbo of thehuman tympaniun.

4. In unsound mechanism, an eccentric cupshaped diaphragm having avolumetric capacity approximatingthe volumetric capacity of one oi. thethree cavities of the human voice anatomy.
